TPP1 — Sorghum bicolor

Summary

SORBI_3002G184450 (SbTPP1) on sorghum chromosome 2 encodes a trehalose-phosphatase (EC 3.1.3.12), a member of the OTSB-like and HAD-superfamily domains that catalyzes the final step in trehalose biosynthesis. The gene is associated with mycose biosynthesis, regulation of secondary shoot formation, glutathione and sucrose metabolism, phenylpropanoid and lignin anabolism, homeostasis, signal transduction, and responses to salinity and cold. It has also been linked to the SALTTL trait. Studies of related genes in other species, such as TPP5, TPP9, and RA3, connect the trehalose-phosphatase family to stress tolerance and developmental processes, though these associations are not yet established in sorghum.
